Amplify - Thermal Energy Review

What is the formula for calculating average temperature?

• (Sum of temperatures) / (Number of samples)

• (Maximum temperature + Minimum temperature) / 2

• (Total temperature) * (Number of samples)

• (Sum of temperatures) * (Number of samples)

What is the difference between kinetic and potential energy?

• Kinetic energy is energy of motion, while potential energy is stored energy.

• Kinetic energy is stored energy, while potential energy is energy of motion.

• Kinetic energy is the energy of an object at rest, while potential energy is the energy of an object in motion.

• Kinetic energy is the energy of an object in a gravitational field, while potential energy is the energy of an object in a magnetic field.

What happens to the speed of molecules when temperature increases?

• The speed of molecules decreases.

• The speed of molecules remains the same.

• The speed of molecules increases.

• The speed of molecules fluctuates.

What is thermal equilibrium?

• The state in which two objects in contact reach the same temperature.

• The condition where heat is continuously transferred between two objects.

• The process of heating an object until it melts.

• The state where two objects are at different temperatures but in thermal contact.
